For a line with multiple instances of "comma within double quotes", I can think of the following perl script - you need to have a header line without this kind of instance so that you know how many comma-separated fields there should be.

#! /usr/bin/perl -w

use strict;

my $n_fields = "";
while (<>) {
    s/\s+$//;
    if (/^\#/) { # header line
        my @t = split(/,/);
        $n_fields = scalar(@t); # total number of fields
    } else { # actual data
        my $n_commas = $_ =~s/,/,/g; # total number of commas
        foreach my $i (0 .. $n_commas - $n_fields) { # iterate ($n_commas - $n_fields + 1) times
            s/(\"[^",]+),([^"]+\")/$1\\x2c$2/g; # single replacement per previous answers
        }
        s/\"//g; # removal of double quotes (if you want)
    }
    print "$_\n";
}
